Patch

A patch is a piece of software designed to fix problems with,
or update a computer program or its supporting data. This includes fixing
security vulnerabilities and other bugs, and improving the usability or
performance. Though meant to fix problems, poorly designed patches can
sometimes introduce new problems. In some special cases updates may knowingly
break the functionality, for instance, by removing components for which the
update provider is no longer licensed or disabling a device. Patch management
is the process of using a strategy and plan of what patches should be applied
to which systems at a specified time.
